Description

Designed for demanding machinery protection applications, the 21000-34-10-00-066-04-02 housing assembly facilitates the external mounting and precise calibration of proximity probes. This rugged explosion-proof enclosure allows engineering teams to install, adjust, or service proximity transducers from outside the machine casing. This eliminates the need to shut down rotating machinery or open critical process seals, optimizing system uptime and enhancing plant safety.

The 21000 Series housing is engineered primarily for Bently Nevada 3300 XL 8mm proximity probes and related transducer systems. By enclosing the probe within a durable, environmentally sealed structure, this assembly protects delicate electronics and cabling from mechanical damage, high velocity process fluids, dust, and corrosive industrial elements.

Features

External Access Design: Enables probe replacement or adjustment without machine disassembly or shutdown.
Explosion-Proof Integrity: Meets demanding safety standards for hazardous area installation when properly sealed.
Heavy-Duty Construction: Manufactured from robust aluminum to withstand severe physical impacts and environmental stress.
Precise Probe Alignment: Internal design maintains strict probe alignment relative to the target shaft for accurate vibration and position measurements.
Cable Protection: Integrates conduit connections to route and shield sensor cables directly from the housing terminal block.

Applications

Steam and gas turbine generator sets
Centrifugal air and gas compressors
Industrial process pumps and electric motors
Cooling tower fans and gearboxes
Hydroelectric generator shafts
